Fracture of porcelain must be a comprehensive way, we must first ensure that the overall structure is reasonable isolation switch disconnectors, and secondly also to strengthen the porcelain manufacturer of choice, you can specify an isolation switch production companies use superior quality and good reputation manufacturer of porcelain products . In addition, you can conduct nondestructive testing technology disconnectors wholesale, porcelain regularly tested. Operating personnel to strengthen the surveillance puffer type isolating switch, particularly the observation of porcelain glued surface. When you run the operation load isolation switch to the right way, such as when operating difficulties should not by force. Porcelain insulator flashover mainly porcelain surface and an inner skirt severe contamination, from small porcelain skirt climb caused. In particular, not only makes porcelain knife, chemical pollution and heavy cement fouling cleaning contaminated areas is extremely difficult, and there are plenty of easy air of industrial dust and corrosive gases insulator flashover caused by discharge, expanding scope of the accident. 2001, is located in northern suburb of Xuzhou Peng market SCIP change occurs 110kV knife support insulator flashover discharge a large area, resulting in porcelain burst. In view of this situation, we can take live cleaning strengthen sweeping efforts to increase Insulators silicone rubber sheds to increase the creepage distance and use water repellent spray coating RTV RTV. Load isolation switch isolation switch _ _ Fuzhou Xi'an by the Xi'an high Huayi power plant.
